Were you ever able to resolve this?
I ended up getting an 1809 image to upload to the console after having much of the same issues. I ended up doing two things and not sure which of the two corrected the issue.
I generated a new WIM file from the install.wim containing only the Win10 1809 Enterprise edition, and I ran the BES Console as Administrator. I’ll do some more testing when this upload completes to determine which item fixed it for me. Also note the WIM file must be on a writable area, based on how the console generates the .driverinfo file in the same path as the WIM - if you are mounting an ISO image containing the WIM, you’ll need to copy the \sources\install.wim into a writable path first.
To generate a .WIM file containing only Enterprise edition, I ran the following:
C:\WINDOWS\system32>dism /get-wiminfo /wimfile:e:\sources\install.wim

The operation completed successfully.
Then, with the Console running elevated (“Run as Administrator”), I was able to import the new WIM file containing only Enterprise edition.
Some handy things to note for troubleshooting is that in the background, the console is running
"C:\Users\<username>\OSDeployment\rbagent64.exe" -o osdtools-extractwimdrivers "D:\temp\win10_1809_ent.wim" "D:\temp\win10_1809_ent.driverinfo"
You can run that command manually in an elevated prompt to see the output, which might be useful in troubleshooting.
Also, whether run from the command line or from the console, a log file is output at
"C:\Users\<username>\OSDeployment\rbagent.log"
